11 Everyday Things That Are Terrifying Under a Microscope

#7. Moths and Butterflies

Butterflies are the most adorable insects in the world. Their gossamer wings are beautifully painted like stained glass windows. Moths aren't nearly as pretty in general, but some, like the luna moth, are downright gorgeous.

Why, nature? Why would you give something so beautiful such a terrifying face? It's like the Fergie of the animal kingdom. Why does it have feathers on its face? And 5,000 eyes? What living creature benefits from having innumerable hideous, terrifying eyes stapled all over its head?

Their faces aren't even any cuter when they're babies, which is normally a rule of the animal kingdom. Here's what a caterpillar looks like up close:

#6. The Human Eye

When you meet someone for the first time, their eyes are one of the first things you notice -- and for good reason. We use them to express emotion and establish who we are speaking to, and to catalog suitable entries in our mental Encyclopedia Masturbatana:

This is a real photograph of a human eye, via electron microscope. The blue part is the pupil, and that twisted orange horror-custard is the iris. But from this angle, it looks like those dead elf marshes from The Lord of the Rings, or something Dante and Virgil had to row across to avoid winged sentries wielding brimstone spears forged from hatred.

#5. Your Eyelashes

At Normal Size:

You see eyelashes pretty much as often as you see eyes. Heck, we even make wishes off of stray ones.

Those are called Demodex, and they're mites that live on everyone's eyelashes. They feed off of the dead skin cells and oil that collect in your follicles. Those are actually just the asses of several Demodex, which is a small portion of the whole beast:

The existence of this is actually astounding because it proves two very important things: 1) There is a God and 2) God has a buddy who bet Him a ton of God-money that He couldn't make a creature entirely out of gray scrota.

Its face is shaped like a human skull, and it has tiny mouth-hands to drag you kicking and screaming into its gaping maw, which looks to contain a gateway to the endless eternal blackness of a starless galaxy of despair. But really, all the horror stems from its beady, soulless eyes, firing a hideous dead gaze that bores through your retinas and rips your mind in two. And then, it feeds. It feeds.

#3. Dental Plaque

At Normal Size:

Plaque is that gunk that forms on your teeth when you don't brush and/or are British. And to be honest, it already looks pretty disgusting at normal size:

But Up Close ...

Your dentist has probably told you that plaque contains a lot of bacteria, but dentists are awful and manipulative and untrustworthy. Cracked? Cracked is trustworthy. You listen to Cracked.

It's full of bacteria. Like, full. Plaque is 100 percent composed of bacteria and "bacterial products," which is the pleasant way of saying "bacteria poop." So you have a fine, pasty mixture of bacteria and shit on your teeth, and if you don't brush, it just builds and builds.

It doesn't take long to build up into a thick layer of biofilm that coats your teeth like whitewash (brownwash?). As this video shows, eight hours is enough time for bacteria to spackle your pearlies with microscopic turds.

#2. Aphids

At Normal Size:

Aphids look like little green watermelon seeds, and really aren't any more horrifying than the average insect. They congregate in large groups, but that's the scariest thing about them:

That completely scientific description isn't terribly far from the truth. Ants bend aphids to their whim, herding them like cattle and even milking them (you may recognize this sentence as the literal definition of insanity). It wouldn't be surprising to see aphids patrolling the halls outside of the queen ant's throne room, looking to rend unwary adventurers limb from limb.

#1. Squid Suckers

Squids are essentially the birds of the ocean. They have beaks, they are formidable predators and there are species large enough to eat just about any damn thing in their environment.

GettyIf they could fly, we'd already be extinct.

As most people know, the tentacles of a squid are covered in suction cups, sort of like those Garfield dolls you can hang on your car window, only drenched in more primal terror. The suction cups don't look like much more than white dots to the naked eye, like sticky bits of poster-hanging glue.

OK, this doesn't even look like a photograph. But it absolutely is. It won the 2008 International Science and Engineering Visualization Challenge in the "This Is Totally a Real Photo, I'm Not Even Lying" division. So in summation, squid tentacles are covered in hundreds of furious gnashing-fanged mouths, because nature didn't think carjackings and AIDS were scary enough.
